IMPROVEMENT IN THE MANUFACTURE OF FERRULES.

Specification forming part of Letters Patent No. 72,093, dated December 10, 1867.

To all whom it may concern:

Be it known that I, ARCHIBALD SHAW, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Ferrule; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to a new and improved ferrule for the handles ot' tools and other implements; and it consists in providing the'interior of the ferrule with oblique spurs or projections disposed or arranged in such a manner as to admit of the ferrule being driven on the handle, and at the same time prevent it from casually slipping oli1 therefrom.

The object ofthe invention is to obviate the necessity of tacks or screws being used to secure the ferrule on the handle, as Well as the punching of the same externally to form a burr to sink into the handle to effect the same end.

In the accompanying sheetof drawings, Figure lis an end view of my invention; Fig. 2,

a longitudinal central section ot' the same shown applied to a handle which is also in section.

Similar letters of reference indicate like parts.

A represents a ferrule, which may be constructed of Wrought or cast metal of any diameter to suit the handle to which it is to be applied. This ferrule has spurs or projections a at its inner side, (three, more or less.) which are ot' oblique i'orm and extend radially inward or toward the center of the ferrule, as shown in Fig. 1. The outer edges of the spurs or projections a, which edges face the center of the ferrnle, are inclined, as shown clearly in Fig. 2, said edges extending from the inner side of the ferrule obliquely upward and outward toward the front end ot' the ferrule, so as to leave front edges, b, at right angles with the inner side of the ferrule, as shown clearly in Fig. 2, the spurs or projections gradually increasing in width from their inner toward their outer ends or front edges, b. By this arrangement the ferrule may be readily driven on the handle, (shown in red,) as the oblique edges admit ot' it, while the front edges, b, prevent the ferrule slipping'oif` from the handle, the wood of the handle closing over said edges b as soon as the ferrule is driven o n the handle.

Thus by this simple means ferrules may be firmly secured ou handles without the trouble ot' nailing or screwing them thereto or punching them externally to form burrs to penetrate the handle.

Having thus described myinven tion, Iclaim as new and desire to secure by Letters Paten t A ferrnle provided internally or at its inner side with oblique spurs or projections, substantially as and for the purpose specified.

ARCHIBALD SHAW.
